The shank is 18 mm across with five grooves, which carries more impact energy than the smaller SDS plus system.\u003c\/p\u003e\n\u003ch3\u003eCan you use SDS max bits in an SDS plus drill?\u003c\/h3\u003e\n\u003cp\u003eNo. An SDS max shank (18 mm) will not go into an SDS plus chuck (10 mm), and an SDS plus bit will not lock into an SDS max chuck. Check your machine before ordering: if it takes SDS plus, choose SDS plus drill bits instead.\u003c\/p\u003e\n\u003ch3\u003eSDS vs SDS max: how do I tell which drill I have?\u003c\/h3\u003e\n\u003cp\u003eLook at the drill's nameplate or manual, or measure an existing bit's shank: about 10 mm means SDS plus, about 18 mm means SDS max. Most compact and cordless rotary hammers are SDS plus; SDS max is found on larger, heavier machines.\u003c\/p\u003e\n","brand":"Bosch Professional","offers":[{"title":"Ø16 mm × 340 mm","offer_id":59095585194365,"sku":"2.608.578.612","price":92.14,"currency_code":"GBP","in_stock":true},{"title":"Ø16 mm × 540 mm","offer_id":59095585227133,"sku":"2.608.578.613","price":107.29,"currency_code":"GBP","in_stock":true},{"title":"Ø20 mm × 320 mm","offer_id":59095585259901,"sku":"2.608.578.626","price":100.4,"currency_code":"GBP","in_stock":true},{"title":"Ø24 mm × 520 mm EXPERT","offer_id":59095585292669,"sku":"2.608.900.239","price":133.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/3297\/3084\/files\/bosch-sds-max-drill-bit-8x-20x320mm.jpg?v=1794470009","url":"https:\/\/fixingsmith.com\/products\/bosch-sds-max-drill-bits-8x-professional","provider":"Fixing Smith","version":"1.0","type":"link"}
